Subject: c= raw space under house
Hi All, I am building a new house. Th= is house has no basement, but has a 24"? crawlspace under the house. &= nbsp; I have lots of time, to create a space for my three sensors, under th= e house. I could also place them in the garage on the concrete = floor. My thought was to enter the crawlspace, and dig a small = pit large enough to allow for elbow room, then line the pit with concrete b= locks to keep dirt away. Perhaps covering the floor area similar= ly. Concrete may not be the best material. I could also p= our a pad or small footing using cement.
Please any thoughts on preparing this space?
Thanks, Ted
